At the pinnacle of elite sport, the difference between winning and losing is tiny, so even marginal improvements can make a crucial difference.

Doctors for Team GB's boxing squad are already trying to improve oral health.

Regular checks

Dr Mike Loosemore, who has worked with the GB boxing team for 17 years and is a consultant at the English Institute of Sport, told the BBC: "I've become aware over the years that dental problems have been interfering with training. It stops them getting that little bit fitter and may have a consequence when they get into the ring and box."

He says things are now improving after regular dental checks were introduced, even if they are not always popular with the boxers.

"They don't like going to the dentist. They'd much rather be training. However, it has made a difference to their teeth and they are spending less time away from their training, and that will make them a better boxer.

"They may not appreciate it now, but hopefully they'll appreciate when they've got a gold medal round their neck in Rio [at the 2016 Olympics]."
